This longer-duration activity involves prototyping a low-power lighting system. It could be used in an off-timetable workshop or across a series of lessons.

Students are challenged to work through the whole design process, and to place a micro-controller (in this case a BBC micro:bit) at the centre of the...

This is a resource aimed at students aged 11-14. It is one of a series that support the use of the BBC micro:bit in the classroom. The pack contains several lesson plans, presentations and student handouts. The first ‘unplugged’ lesson introduces students to how programmable systems work, the second they are walked...

This activity, suitable for a multi-lesson sequence or a single extended session, challenges students to design and prototype a simple motion-sensing alarm. The device is intended to prevent theft or the accidental picking-up of a bag.

Motion is sensed using the accelerometer built-in to the BBC micro:bit,...

In this activity, students create colour images from satellite data. This allows them to study how different surfaces reflect different wavelengths of light, how coloured images are created using an RGB model, and how band combinations can be chosen to examine a particular landscape effectively.

Using a spreadsheet as a grid of 'pixels', this computing activity teachers how 1's and 0's can store image data. The classroom exercises use images with increasing pixel resolution, looking at how this affects the clarity of the image. Moving from black-and-white images, the students then use grids of colour...

Dijkstra's algorithm finds the shortest path for a given problem. Dijkstra's algorithm can be used to find the shortest route between two cities. This algorithm is so powerful that it not only finds the shortest path from a chosen source to a given destination, it also finds all of the shortest paths from the...

After learning about flooding, students consider the design problems caused by its early detection. Students are introduced to moisture sensors, and can build their own using the instructions provided or use a ready-made version. This is connected to the BBC micro:bit and used as an input device. After processing...

This classroom resource for secondary computing lessons outlines the history of development of computers. It covers thousands of years of history, including:

• the abacus
• log tables
• the calculators of Pascal and Leibnitz
• Jacquard looms
• Babbage's Difference Engine and...

This series of five one-hour lessons covers computer networks at secondary-school level. The objectives of the lessons are:

• Describe what a network is, the difference between a LAN and a WAN and identify three network topologies.
• Describe pieces of hardware that are needed in a network.
...

This series of three lessons introduces Python programming to students in secondary school. The lesson objectives include:

• Creating simple code including the input and print scripts
• Using "If statements" to make a decision
• Using the random function in programs

Artificial intelligence (AI) is a disruptive technology, meaning that it is significantly changing the way that people, businesses, and industry interact. To put it in context, the invention of the wheel, electricity, TV, and GPS are all disruptive technologies that changed the way in which society worked.

This activity allows students to investigate how images are produced from data streams by using first a spreadsheet and then an image-processing program. They then go on to see how the usefulness of such a monochromatic image may be enhanced by using lookup tables and calibration. The materials used focus on the...

This short activity introduces students to the ideas of the footprint and resolution of an image, asking them to choose and use appropriate methods to calculate how these quantities would change as they moved a camera to a series of vantage points above the surface of the Earth

In this activity students take on the role of Earth observation scientists submitting a request for an image they would like for their research. This gives them the opportunity to consider the possibilities of pictures taken from orbit (and the limitations) and to write scientifically for a specific audience. It...
